Product Details

1,11-Diamino-3,6,9-trioxaundecane CAS 929-75-9 for Polyether Diamine Intermediates

1,11-Diamino-3,6,9-trioxaundecane, also known as tetraethylene glycol diamine, is a polyether diamine intermediate containing two terminal primary amine groups and an extended ether-linked chain. Its polyether diamine structure makes it useful in organic synthesis routes where terminal amine functionality, ether-chain flexibility and polarity adjustment are required for further derivatization.

This product may be used in pharmaceutical intermediate synthesis, fine chemical synthesis, specialty organic intermediate preparation and selected amine-based transformations. In B2B sourcing, buyers usually need to confirm assay, amine value, water content, appearance, color, related amine impurities, residual solvents, storage conditions, packaging, transport classification and documentation availability before purchase.

Chemical Structure

Key Applications

Organic synthesis intermediate: Used as a polyether diamine building block for introducing terminal amine groups and ether-chain functionality in downstream synthesis.
Pharmaceutical intermediate synthesis: May be used as a starting material or intermediate in selected pharmaceutical intermediate routes, subject to specification and process requirements.
Fine chemical intermediate: Suitable for specialty chemical synthesis where diamine structure, ether-chain flexibility, polarity adjustment or chain extension is required.
Polyether diamine intermediate: The extended ether-linked chain and two terminal primary amine groups may support selected routes requiring flexible diamine structure or spacer-type building blocks.
R&D and process evaluation: Can support laboratory evaluation, route screening and process development for organic synthesis projects.
Further derivatization: The terminal amine groups may be involved in acylation, alkylation, condensation, salt formation or other downstream transformations depending on the synthesis route.

Sourcing and Documentation Support

Specification confirmation: Assay, amine value, appearance, color, water content, related amine impurities, residual solvents and physical state can be reviewed according to buyer requirements and supplier confirmation.
COA and SDS support: COA and SDS may be provided for confirmed products, subject to product, batch and supplier confirmation.
Packaging review: Packaging options can be checked according to product properties, order quantity, viscosity, moisture sensitivity, storage requirements and transport classification.
Export and logistics discussion: Shipment feasibility, dangerous goods classification, trade term and destination requirements should be confirmed case by case before quotation or shipment.

Packaging and Logistics Considerations

1,11-Diamino-3,6,9-trioxaundecane is commonly handled as a liquid polyether diamine material. Suitable packaging should be confirmed according to product properties, order quantity, storage conditions, supplier specification and transport route.

Packaging may include small bottles, small drums, 25 L drums, 200 L drums or other suitable formats, subject to supplier confirmation. For polyether diamine products, packaging tightness, moisture protection, odor control, viscosity and compatibility with amine materials should be reviewed before shipment.

Sea, air, courier, LCL or FCL shipment feasibility should be evaluated case by case according to the latest SDS, transport classification, package size and destination requirements. Import clearance, local duties, taxes and destination compliance should be confirmed by the buyer or their appointed import agent.

Common trade terms may include FOB China port, FCA warehouse, CFR/CIF destination port or DAP destination where applicable. Final shipment arrangement depends on product classification, order quantity, destination and buyer import capability.

Safety and Storage Information

The following safety information is for general reference only. Final hazard classification, handling requirements, storage conditions and transport conditions must be confirmed according to the latest SDS and shipment documents.

Handling: Handle in a well-ventilated area with appropriate personal protective equipment and avoid direct contact with skin, eyes and clothing.
Storage: Keep the container tightly closed and store in a cool, dry and well-ventilated place. Protect from air, moisture, light, heat and incompatible materials.
Transport confirmation: Transport classification, labels and packaging requirements should be verified according to the latest SDS, dangerous goods classification report or shipment documents.
